ENCANDESCENT-LAMP SOCKET.

Specification of Letters Patent.

Patented Oct. 16, 1906.

' Application filed June 5,1903- Serial No. 160,151-

To all], whom it may concern.-

Be it known that we, CLARENOE O. SIBLEY, a resident of Perth Amboy, Middlesex county, New Jersey, and GEORGE A. Lurrz, a resident of N ew'York, borough of Brooklyn, State of New York, citizens of the United States, have invented certain new and useful Improvements in Incandescent-Lamp Sockets, of which the following-is a specification.

The object of our invention is to provide improved means for insulating the lead-in wires or conductors ofnn incandescent-lamp socket from the operative parts and from the metallic shell and cap covering the same;

and to this end we provide an insulating-lining for the metallic cap that has an integral apertured extension passing through an open ing in the cap and means for securing the lining to the cap.

Reference is to be had to the accompanying drawings, forming part hereof, wherein Figure 1 is a side view of a socket embodying our invention. Fig. 2 is a central section through the cap and its lining. Fig. 3 is a side view of the insulating-lining. Fig. 4 is a sectional viewof the cap. Fig. 5 is a detailed view of the ring for holding the cap and lining together. Fig. 6 is a centralsection showing modified means for holding the cap and lining together, and Fig. 7 is a plan view thereof.

Similar numerals indicate corresponding parts in the several views.

In the drawings the numeral 1 indicatesa shell or casing adapted to. inclose the opera tive parts of an incandescent-lamp socket of any suitable construction, and 2 indicates a capadapted to be connected to the shell by any suitable or well-known means, as a pin-and-slot connection, as at 3 4.

At 5 is indicated a lining for cap 2, which is to be made of any suitable insulating material, such as rubber'or porcelain, and the lining 5 has an extension or projection 5 of similar material, shown as made in one piece or integral with lining 5, and at 5 the lining audits projection 5 are shown provided with an aperture or here leading into cap 2. The

and by means of the lining 5 and projection 5 are insulated from cap 2. We have shown means for detachably connecting the lining 5 with cap 2, as follows: On the exterior of projection-5 close to the outer surface of cap 2,

is a groove or recess 5, in which a split ring 6 fits, as shown in. Figs. 1 and 2. The ring 6 by engaging cap 2 prevents projection 5 from being pulled through opening 2, and as lining 5 is within cap 2 the lining and its projection are securely attached to the cap.

In Fig. 6 the ring 6 is interposed between lining 5 and cap 2, and in this case'the lining is shown provided near its lower edge with a recess 5 and the cap 2 has an internal groove or recess 2 the ring G-fitting in said grooves or recesses, and thereby holding said linin withinthecap. It will be also understoo that by allowing the lining 5 to rest upon the usual base withi'n the shell 1 the apertured projection 5* will be prevented from slipping inwardly through the aperture 2 in cap 2,

while the latter is held upon 'shell 1 if the ring 6 should be removed.

By means of our improvements the linin 5 and its projection can be readily attache to and removed from cap 2, and thelining and its projection aflord perfect insulation between the cap and the lead-in wires-and their operative parts.

Having now described our invention, what we claim is+ 1. An incandescent-lamp socket having a cap provided'with atop opening, a lining within said cap provided with an apertured projection passing through said opening, and

a ring engaging the cap and serving to hold the lining and its projection in position, substantially as'described.

2. An incandescent-lamp socket rovided with a cap having a top opening an a lining of insulating material provided with an apertured projection passing through said opena ing, said pro ection having a groove or recess without the cap, and a ring located in said groove or recess adapted to engage the cap to preventidg said filojection from slipping inold the limng and its gJIOJQCtIOII in position, wardly through the. aperture in the cap, suh- 10 substantially as descri ed. stuntially as described.

3. Inan incandescent-lamp socket the cap CLARENCE (J. SIBLE Y. 5 provided with an opening in its top and an GEO. A; LUTJ.

insulating-lining having an apertured insu- \Nitnesses: iating projection passing through said open- GEO. D. PETMAN,
